Fin: A Ring That Turns Your Hand Into a Touchscreen Interface

Here’s a smart device that brings gesture controls to your finger – literally. The smart ring is capable of controlling any smart device, and it looks a bit like using a magic touch. The best part? It’s not on your face. Fin’s tiny ring uses Bluetooth and Low Energy Technology to control all sorts of devices like televisions, DSLR cameras, music players, home appliances, and even your car. It’s great for users with accessibility troubles, but I’d also imagine it will be perfect for air guitar.
